- Personal Protective Equipment (PPE): Wear appropriate PPE including chemical-resistant gloves, eye protection (safety goggles or face shield), and protective clothing.
- Ventilation: Use in a well-ventilated area. If adequate ventilation is not available, use respiratory protection.
- Storage: Store in a cool, dry, well-ventilated area away from incompatible materials and direct sunlight. Keep container tightly closed.
- First Aid: In case of contact, immediately flush affected areas with plenty of water. If swallowed, do NOT induce vomiting. Call a poison control center or doctor immediately.
- Disposal: Dispose of contents and container in accordance with local, regional, national, and international regulations.
Setup
Before beginning the cleaning process, ensure the equipment is de-energized and cooled down. Prepare the work area to contain any runoff and ensure proper ventilation.
- Ensure all necessary PPE is readily available and worn.
- Gather all required tools: spray applicator (e.g., pump sprayer), brushes (if needed), water source for rinsing, and collection containers for runoff.
- Isolate the system to be cleaned from power sources and ensure it is not operating.
- Protect surrounding areas from overspray or runoff using tarps or plastic sheeting.
Operating Instructions
Nu-Calgon Special HD Cal Clean is a concentrated product and must be diluted before use. The dilution ratio may vary based on the severity of the buildup.
Dilution Guidelines:
- Light Buildup: 1 part cleaner to 5-10 parts water.
- Moderate Buildup: 1 part cleaner to 3-5 parts water.
- Heavy Buildup: 1 part cleaner to 1-2 parts water.
Application Steps:
- Prepare the diluted solution in a suitable spray applicator.
- Apply the solution evenly to the coil or surface to be cleaned, ensuring complete saturation.
- Allow the solution to penetrate and react with the deposits for 5-15 minutes. Do not allow the solution to dry on the surface. For stubborn deposits, agitation with a soft brush may be necessary.
- Rinse thoroughly with clean water. Ensure all cleaner residue is removed. Rinse from top to bottom to facilitate drainage.
- Inspect the cleaned surface. If necessary, repeat the application process for heavily soiled areas.
- Restore power to the system once the cleaning and rinsing are complete and the system is dry.
Note: Always test on an inconspicuous area first to ensure compatibility with the surface material.
Maintenance
Regular cleaning with Nu-Calgon Special HD Cal Clean can help maintain optimal performance and extend the lifespan of your equipment. Establish a cleaning schedule based on usage and environmental conditions.
- Frequency: For residential use, cleaning every 6-12 months is often sufficient. Commercial or industrial applications may require more frequent cleaning (e.g., quarterly).
- Inspection: Regularly inspect coils and surfaces for signs of buildup. Early detection of deposits can prevent significant performance degradation.
- Post-Cleaning: After cleaning, ensure all equipment is thoroughly rinsed and dried to prevent corrosion or residue buildup.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Cleaner not effective | Incorrect dilution ratio; Insufficient contact time; Extremely heavy buildup. | Increase concentration of cleaner; Extend contact time; Apply multiple applications; Use agitation (brushing). |
| Residue left after rinsing | Incomplete rinsing. | Rinse more thoroughly with clean water until no foam or residue is visible. |
| Strong odor during cleaning | Inadequate ventilation. | Ensure proper ventilation in the work area. Use respiratory protection if necessary. |
